    • A contact for a connector, which includes two opposed contact elements for receiving therebetween a male contact of a mating connector. Each the contact element is provided with one or more protrusions on an opposed surface for embracing the male contact. Protrusions of the two opposed contact elements extend to that portions of the opposed contact elements which are devoid of the protrusions so as to overlap each other before the male contact is inserted between the contact elements. With this arrangement, even if the male contact is very thin, pressing force required to securely pressing the male contact by the contact elements is certainly obtained. The contact and the male contact are securely contacted without any torsional force and other forces which would otherwise be caused on these contacts.
    • 用于连接器的触点,其包括用于在其间接纳配合连接器的阳接触件的两个相对的接触元件。 每个接触元件在相对的表面上设置有一个或多个突起,用于包围阳接触。 两个相对的接触元件的突出部分延伸到没有突起的相对的接触元件的部分,以便在阳接触件插入在接触元件之前彼此重叠。 通过这种布置,即使阳接触非常薄,肯定地获得了通过接触元件牢固地按压阳接触所需的压力。 接触件和阳接触件牢固地接触而没有任何扭转力和其他在这些接触件上引起的其它力。

    • Apparatus for removing and collecting fiber waste from a creel stand having multiple, juxtaposed creel sections including an air suction/blower blowing a first air stream across the top of the creel sections and creating a second air stream flowing across the bottom of the creel sections. An air deflector reciprocating across the top of the creel sections deflects the first air stream downwardly through the creel sections. A bottom plenum beneath the creel sections receives the air stream from the creel sections and confines and directs the second air stream to the suction/blower. A second blower blows air through the bottom plenum toward the suction/blower to assist the suction/blower in creating the second air stream. A plurality of baffles are included in the bottom plenum to provide laminar air flow therein.
    • 用于从具有多个并列的纱架部分的纱架架上去除和收集纤维废料的设备,包括空气抽吸/鼓风机,吹扫第一空气流穿过纱架部分的顶部,并产生流过纱架部分底部的第二气流。 穿过纱架部分顶部的往复运动的导风板将第一气流向下偏转通过纱架部分。 在筒子架部分下面的底部增压室接收来自筒子架部分的空气流并限制并将第二气流引导到吸入/鼓风机。 第二鼓风机将空气通过底部增压室吹向抽吸/鼓风机,以帮助吸入/鼓风机产生第二气流。 多个挡板包括在底部增压室中以在其中提供层流气流。
